Abstract: The different illustrative embodiments provide a method and system for watering plants. A map of an area is received and a determination is made using a processing unit as to whether the area needs water. If the area needs water, current constraints are identified and a determination is made using the processing system as to whether the current constraints allow for watering. If the current constraints allow for watering, a watering solution application plan is generated using the processing system, and the watering solution application plan is executed using a mobile utility vehicle.

Abstract: A system and method for positioning a mobile machine, such as a robot, using a tether line connected between two mobile machines. A first mobile machine, such as a boundary vehicle, is controlled to move along a path, such as a boundary defining an area. The first machine employs a localization device to determine and maintain its position on the path. A tether line is connected between the boundary vehicle and a second mobile machine, such as a roving vehicle. The first machine determines the position of the second machine relative to the first machine from a length of extension and angle of the tether line. The first machine controls movement of the second machine to perform a task or mission, such as a task performed in the area defined by the boundary.

Abstract: Retractable line guidance for a self-propelled machine, such as a self-propelled lawn mower, is provided by an operator moving a string or line to control the speed and direction of movement of the machine. A retractable and extendable line is mounted on the machine and is under tension in a retraction direction when the line is extended. A length of extension of the line is monitored, and a speed of movement of the machine is controlled in response to the length of extension of the line to maintain the length of extension of the line at a selected length. An angle of the line with respect to the machine is monitored, and a direction of movement of the machine is controlled in response to the angle of the line to maintain the angle of the line at a selected angle.

Abstract: A method and apparatus for supporting end-to-end quality of service (QoS) reservations for an implicit reservations model are provided. The invention teaches how to implement implicit resource reservations using the open-standard Resource and Admission Control Function (RACF). A request for resources for a given reservation between an originating and a terminating point in a network is received. A central controller for that domain processes the request for a given domain to determine whether routes for said reservation are available and whether necessary bandwidth for said reservation is available. An implicit reservation and a release of the bandwidth are respectively accomplished with a specific number of messages. If the routes and bandwidth are available, the reservation for the given domain is confirmed and the reservation request is passed to another central controller for a next domain having resources required to satisfy the reservation request.

Abstract: A method for regenerating a boundary of an area for containing a mobile machine is provided. An emitter is detected in an area designated to contain the mobile machine. In response to detecting the emitter, a function is performed. In addition, the emitter is reapplied on a predetermined time interval basis over an existing detected emitter to minimize deterioration of a strength of the emitter due to time and environmental factors.

Abstract: An apparatus and method for detecting the presence of a slippery material, such as ice, on a surface and for taking action to mitigate the potential hazard presented by such material automatically with little or no human intervention. In accordance with an illustrative embodiment, a mobile machine, such as a robot, is controlled to move automatically across a surface along a path. The mobile machine automatically detects for the presence of a slippery material on the surface as it traverses the surface. The mobile machine automatically takes an action to mitigate the slippery material in response to the detection of the slippery material on the surface.
